For calculations of microfield distribution function P(E) in a nonideal hydrogen one and two-component plasma the method proposed by C.A. Iglesias was used basing on a pair correlation radial distribution function. Numerical calculations of P(E) were made for different plasma parameters. P(E) were determined in a frame of two pspeudopotential models which take into an account both, the quantum-mechanical effect and screening field effects. One is basing on the Deuscht potential the other one on the Kelbg potential. The results obtained by applying the two models for a one and two-component plasmas are compared with those given by Holtsmark, Hooper, Iglesias and other authors.
